I absolutely have observed mods on Lemmy engaging in the same shitty behaviors (I am sitting on a post about a little cabal of !progressivepolitics@lemmy.world people who seem to be trying to rig the discourse in a particular direction to meet their electoral goals). But the simple fact of it being less centralized and more transparent (and with more of a culture of effective pushback against the mods) makes it a lot harder. They can’t just say “lol get fucked” like the mod from this post did and have that be the end of the story.
